Submersible centrifugal pump
B80 KGK G1/G2

Fields of applications:
Powerfull and robust immersion centrifugal pump with plain bearing, support stand mounted on roller bearings and IEC standard motor. The KGK G1/G2 series is designed for medium to high pump capacities under continiuous operation.

Features:

  • Robust bearing housing with lifetime-greased roller bearings 
  • Independent support of motor and pump
  • Housing made of reinforced plastic (PP or PVDF)
  • Plain bearings made of PTFE/Al2/O3 or SiC/SiC (optional with external flushing) 
  • Vapour seal to protect driving elements (optional with fluid barrier or as mechanical seal) 
  • Version "G" with GRP-coated shaft guide tube and rising tube
  • Driven by IEC standard motor as per efficiency level IE 2 in accordance with Directive 2005/32/EC 

 

Sealing system:
Static-dynamic vapour seal or mechanical seal

Immersion depth:
500 - 4000 mm and additional suction pipe extension up to 2000 mm

Benefit:

  • Optimal absorption of axial and radial loads
  • Vibration-free operation
  • Vapour seal as rotary shaft seal or mechanical seal 
  • Roller bearings with lifetime grease lubrication
  • Long service life and high level of operational safety 
  • All parts coming into contact with the liquid are made of corrosion resistant plastics
  • No housing screws located in the wetted area
  • Optional external flushing to protect guide bushing when pumping solid containing liquids
  • GRP-coated version "G" increases strength and limits longitudinal expansion
  • Also for deep vessels and containers

Three-phase motor 0,25 kW - 15 kW for centrifugal pump B80 KGK G1/G2

IEC motor
  • IEC standard motor as per efficiency level IE 2 (≥ 0,75 kW) in accordance with Directive 2005/32/EC
  • 2-pole with 2900 1/min for high capacity
  • 4-pole with 1450 1/min for circulation duty
  • 3 phases 400 V / 50 Hz, 0,37 kW up to 15 kW, protection class IP 55, insulation class F*
